Hi,
do we (I) have edit permissions on the tutorial documentation?
I tried to follow the first steps of the tutorial, and the instructions are
out of date for the develop head. Some googling resulted in the solution,
but for me it still does not execute correctly.

x86 linux boot is a component of the '--length long' regression.
You need the kernel and disk image that are installed when the regression
is run.

Do we still support python2.7?
I am adding some functionality and it is cleanest in python3, but the code
will fail if running in python2.

At the ISCA workshop, someone (Jason?) had a prototype of support for
dynamic libraries.
I could not find this on reviewboard. Maybe I missed it.
Is there a patch for this, or has the code not been released?

Hi,
I just build the top of tree, and tried to run helloworld using --cpu=kvm

The test fails.

There are patches under review to get this working, can we get those in?
It seems to me that it should be possible to directly import kvm or qemu

Does the community agree, or am I missing something.

I am running a set of checkpointed samples via the new simpoint patch.
it seems that when the simulation ends at the end of the sample, gem5
returns a non-zero code (127 I think).
Is this intended?
when gem5 reaches the end of the program via exit() it returns 0.
I have verified that x86 kvm works fine on AMD platforms, but fails on

Any hints about how to narrow down the cause (other than diving into gdb,
